I read some finance textbook when I was just starting out, I think it was "introduction to derivatives and risk management". That helped too. It's a good, gentle introduction to derivatives and you can skip most of it unless you want to work for an investment bank.
I think the best way to learn is to just watch stocks overtime, and read up on the news relevant to them. That's really why I play with options, it keeps me plugged into following the movements of a bunch of different stocks, so I learn a lot about what makes them behave in certain ways. Definitely stay away from paid classes on investing or trading, those are almost all scams - if a "successful trader" has to teach paid classes they're not actually successful. And re: my strategy of trying to identify short term movements that make something under/over-valued and hoping it will correct, just realize that sometimes the market can stay irrational longer than you can remain solvent, and sometimes you just need to take the loss and get out.
One more thing I forgot. When I refer to "news" I mean real news. A lot of financial news websites are complete bot-written vacuous garbage. Real news is things like deals happening or falling through, large orders, interest rates, lawsuits, recalls, earnings, trade deals, etc.
I mostly stick with SPY and it keeps climbing. I just buy 30-45 days out calls that are slightly out of money. Usually sell them at 20-30% profits with in a few days.
Of course, it is only 1-2% of my regular investments in index funds. Too risky to put any real money in options.
The thing I'd be worried about with medium term SPY calls is that you will be completely wiped out by a recession. Or even if a correction happened like in December and didn't rebound fast enough. Of course during a bull market that's a fine strategy (as long as theta/IV don't eat any potential profits) , and if you are socking away your gains it's probably fine. But if you are just growing your options allocation by 50% every couple weeks and then throwing it all back into the same position, eventually your double or nothing will come up nothing. Just something to consider

Just joking. Don't downvote please
Rather than continually making bets just for the sake of making bets I only make trades when I think a stock overreacted to bearish news (meaning it's likely to rebound to its old price given that the business' fundamentals are unaffected), was oversold due to underperformance of other stocks traded alongside it, or is greatly overvalued due to some irrational hype (Lyft and most canadian weed stocks). And I sell quickly if the option loses a lot of its value or if the option greatly appreciates to lock in profits and limit losses.
